Application filed. May 20, 1913. Serial No. 768,740.

To all whom it may concern Be it known that I, URIAI-I Home, a citizen of the United States, and a resident of Gornwall, in the county of Lebanon and State of Pennsylvania, have invented a new and useful Improvement in Filters, of which the following is a specification.

My invention is an improvement in filters, and has for its object to provide a device of the character specified, especially adapted to be attached to the discharge pipe from the. collecting surface as for instance, a roof, and

to be arranged between the said collecting surface and the clstern and havlng means for thoroughly purifying and clarifying the water before admitting the same to the cistern, and also having means for deflecting the first water discharged-from the collecting surface out of the filter and away from the cistern.

In the drawings :Figure 1 is a longitudinal section of the improved filter, Fig. 2 is a section on the line 22 of Fig. 1.- Fig. 3, 4.- and 5 are sectional views of modified constructions, Figs. 3 and 4!: showing the construction only partially, and Fig. 6 is a top plan view of Fig. 5 with a part of the cover broken away. a

In the embodiment of the invention shown in Figs. 1 and 2, a casing is provided, consisting of upper and lower sections 1 and 2 respectively, the said sections being of cy lindrical form and the section 2 .is provided with a supporting ornamental base 3. The upper edge of the lower section 2 is annularly enlarged as indicated at 4, and the lower end of theupper section seats within the enlarged upper end of the lower section. The lower section is provided with a partition or diaphragm 5, near its lower end, the

said diaphragm being spaced above the base.

A pipe 6 leads from above the diaphragm vided with two annular series 11 and 12 of openings, the openings12" being at thepartition or diaphragm 5, and the openings 11 being spaced above thesame. A pipe 13 extends through the diaphragm at the axis of the casing 1-2, the said pipe extending through and beyond the base 30f the casing and to a point near the top 9 of the auxiliary casing .8.

The section 1 of the main casing is provided nea'r its lower end with a transverse diaphragm ltof perforate material, and the upper end of the saidsection is beaded as indicated'at 15, and is engaged by a cover 16. A pipe 17 extendsthrough the cover and a cup or receptacle 18 is arranged in the said section of the casing justbelow the pipe: 17, the said pipe delivering to the cup. The cup 18 is provided with an outlet 19 in its bottom, and the said outlet delivers into the. en larged upper end 20 of a pipe 21. The pipe 21 isarranged adjacent to the side wall of the section of the casing, extending from the cup 18 to a point near the diaphragm 14:,

where the saidpipe opens with a lateral elbow 22, through the sidewall of the section 1 of the casing 12. y The section 1 of the casing is provided with a lateral opening 23, the edges of the opening being beaded as indicated at 24, to strengthen the same. The cup .18 isprovided on its outer face with oppositely arranged perforated lugs 25 and 26, and chains 27 and 28 respectively are connected with the said lugs. The chains extend through the opening 28, and the free end of the chain 27 is provided with a ring 29 of larger diameter than ,theopening 23 to prevent the passage of the ring through the opening.

.The cup is provided with a depending pin 30 at the center of its bottomyand the said pin extends into a bearing '31 formed in the periphery of the enlargement 20 of the pipe 21. The said pin supports the upper endof the pipe 21, holding it in a certain position with respect to the cup. The upper section 1 of the casing is partially filled with filter- .ing material indicated by the reference numeral 32, the said material fitting around the pipe '21 and resting at its lower end on the diaphragm. 1 1. The said material fills the section of the casing to the enlargement 20 of the pipe 21." By means ofthe chains 27 and 28, the cup 18 maybe rotated on the pin 30, to bring the outlet 19 thereof above the enlargement 20 of the pipe 21, or above the filtering material in the upper section of the casing It will be noted that the lower free edge of the outlet 19 of the cup is spaced above the upper free edge of the enlargement 2O to-permit such rotation of the cup. When the outlet 19 is above the enlargement 2-0 of the pipe, the water which enters the casing through the pipe 1? from the roof or other Jlace'cf collection aasses throne-h the oioe 7 l c l 1 2021' 22"to a suitable place or' discharge without aiiecting or without interference from the filter. l l hen however, it is desired to filter tne water and "to pass it into the cistern, the cup 18 is oscillated, by means of the chains 2! and 28, to bring the outlet 19 thereof away from over the enlargement 20 of the pipe. The water now passes into the upper section of the casing and down through the filtering material into the lowersection of the casing, passing through the perforated diaphragm as it leaves the filtering material.

The pipe 113 communicates with the cistern, and whenever the water in the filter risesabove the upper end of the pipe 13, it will flow into the cistern. A certain predetermined amount of water depending upon the height of the upper end of the pipe 13,

' above the diaphragm 5 is always retained in the lower section of the casing and may be drawn off for use through the valve casing faucet 7. The water in the lower section ofthe casing enters the auxiliary casing 8 --'.throughthe openings 11 and passes up in the said auxiliary casing until it reaches the top of the pipe 13 through which it flows into the cistern.

1n the construction shown in Fig. 3, the auxiliary casing'S is replaced by a transverse partition or diaphragm 33, arranged in inclined position transversely of the lower section 2 of the casing, and at its lowest pointa discharge pipe 8% leads downwardly from the said partition to a point below the upper end of the discharge pipe 13. The escape pipe 35 for air leads from the partition 33 and opens through the side of the casing section in'the same manner as the pipe 10. With this construction a certain amount of water will always be retained in thelower section 2 01 the casing, since no water can flow through the pipe 13 until the water reaches the upper end thereof. The trapped air below the partition 33 escapes through the pipe 35.

In'the construction of Fig. 4, the discharge pipe 36 extends through the partition 5, and above the same, and the said pipe is provided with a gocseneck or return bent portion 37. The airdischarge pipe 38 extends from the apex of the arched connectionbetweenthe body portion 36 of the said pipe and the return bent portion 37. As the water passes through the perforate diaphragm 1 1-, it must rise to the arched connection between the portions So and 37 of the said pipe before it can flow into the cis tern. The trapped air escapes through the pipe The improved filter is arranged between the cistern and the place of collection, that is, between the root and the cistern. The discharge pipe from the root connects with the pipe 1?, while the pipe 13 delivers into the cistern. Thus the water will be thoroughly filtered and clarified before it reaches the cistern.

r-iny impurities in the way of sand and the like that may enter the lower section 2 01 the casing will be deposited on the parti tion 5 and will not flow into the cistern. The upper portion 1 of the casing may be easily removed -for cleaning or for renewing the filtering material or any other purpose. The lower section is then accessible for cleaning or repairs.

[is is known, the first water that runs away from the root dirty, since it catches the impurities and dirt from the roof which has collected since the last rain. In use, the first discharge from the roof would be permitted to pass out through the pipe 20. As soon as the water shows clear discharging frmn the said pipe, the cup 18 will be'oscillated to deliver on to the filtering material.

It will be understood that the filter will be arranged as may be desired, between the place of collection and the receptacle for the filtered water, and the arrangement will depend upon the relative position of the receiv ing and collecting elements. If for instance, the said receiving and collecting elements are at the same level, the filter would occupy a position either horizontal or approximately so, and only such changes would be made as vould be necessitated by the change in relative position. is for instance with the construction of Fig. 1, the discharge pipe 13 might be arranged as shown or the said pipe might extend laterally from the casing, and the trapping device would be changed to a horizontal position. A construction of this character is shown in Figs. 5 and 6, wherein the casing 39 is provided at one end with a lateral extension 40, for receiving liltering material designated at 41, and a screen 42 is arranged between the casing 89 and the extension. The casing is provided with a base 13, and with a diaphragm 41 just above the base. The casing is also provided with a lateral outlet 15, through the diaphragm, the outlet having a controlling mechanism 4:6 outside the casing. The discharge pipe 17 extends through the diaphragm and above the same, and the said discharge pipe may be straight, as shown, to deliver directly below the casing or may be bent laterally as indicated at e8 in dotted lines to discharge laterally with respect to the casing.

The casing and extensions are provided with a cover 49, and the inlet pipe opens through the cover at the end remote from the casing. The said inlet may be vertical as shown in full lines at 50 or may be lateral as shown in dotted lines at 51.

A cup 52 is arranged in the extension below the inlet pipe, the said'cup having an outlet 53, delivering eccentrically to the cup, and a pin 54 depends from the center of the cup and engages a bearing 55 in the vertical portion of a partition 56 the said parti' tion comprising the vertical portion, as shown. The cup may be provided with chains 57, similar to the construction of Fig. l, for rotating the cup to bring the outlet over the filtering material on one side of the partition 56, or over the compartment separated from the body of the extension by the partition, the said compartment having a discharge outlet 57 The filtering material is arranged between the screen 42 and the partition 56. A frustoconical shield or hood 58 incloses the upper end of the discharge pipe 47, the said hood being arranged with its small end upward, and the small end is provided with a trapped air discharge pipe 59, the said pipe extending to near the cover l9 of the casing.

The shield or hood is provided with annular series of outlets 60, near and at its lower end for admitting the water within the hood, the construction being practically the same as that shown in Fig. 1. The filtering material is arranged below a screen 61, and the operatic-n is practically the same as the construction of Fig. 1.

The first flow from the place of collection is discharged through the discharge outlet 57, and as soon as the water from the said outlet shows clean, the cup 52 is rotated to bring the outlet 58 above the filtering material. The water flows down through the filtering material and through the screen 42 into the casing proper. Here it passes through the opening 60 and when it rises above the upper end of the discharge pipe, the water may flow into the place of storage. When the cover 49 is removed, access is permitted to the interior of the casing, for cleaning the same or for removing the filtering material and replacing it with fresh material.

The portion 40 of the casing is described as an exte'nsion'for convenience. The casing however, comprises both the vertical portion 39 and the horizontal portion 40. The construction shown in Flgs. 5 and 6 may be arranged between the place of collection and the place of storage for the waterwhen the relative height of the said place of connection and place of storage is not so pronounced. When the place of connection is at considerable height above the place of storage, the form shown in Figs. lto 4 are preferable.

I claim A filter comprising upper and lower sections detachably connected together, the lower section having a base and a bottom above the base and provided with a delivery pipe extending through the bottom, the upper section having a transverse perforated partition near its lower end for supporting filtering medium, a waste pipe held in the upper section at one side thereof and delivering laterally from the section near the partition, a removable top for the upper section having an inlet pipe extending through the same, means between the said lnlet pipe and the waste pipe for receiving the water from the inlet pipe and delivering it to the waste pipe or to the interior of the filter, and means in the lower section in connection with the delivery pipe for preventing the direct flow of the water from the filter through the delivery pipe. 1
